It's kind of hard to tell you where to look if we don't know which ones you have, which is pretty much impossible to remember. The best possible help is to simply go through the mansion room by room one more time.
However, there are a number of secret rooms, such as the treasure room through the mouse hole in the Butler's Room, and the boarded up room accessible from the roof. I believe there is a boo in either or both of those, so check those. If you don't know how to get into them, check a walkthrough.

Just try to look for the boo in every room that you have unlocked. If something on your map is gray, then you should go into that room and there should be a boo.
